ATECC608A I2C Notes

Here be dragons

WARNING: AS THE DEVICE CAN BE CONFIGURED ONLY ONCE, PLEASE BE WARNED THAT YOU MIGHT EASILY BRICK THE CHIP! USE AT YOUR OWN RISK!

Circuit

Please make sure to use proper circuit for ATECC608A with pullups and decoupling capacitors when hooked to a MCU. A Raspberry Pi might also work without external components just using internal pullups.

ASAHIネットのDS-Liteの終端(AFTR)を取得する

ASAHIネットがDS-Lite対応したので、 自宅の適当なLinuxルーターにて設定しようとして詰まったAFTR取得に関するメモ。

Linuxルーターを使ってる人向けのニッチなものだけど、情報として残しておく。

終端の情報公開について

# ipsj.cls を upLaTeX 用にしてみる（源ノ明朝・源ノ角ゴシックを使う）
# https://gist.github.com/trueroad/c44312923bf02226c2274388941d0453
#
# ipsj.cls は pLaTeX 専用のようなのですが、
# 試しに upLaTeX で使えるようにした up-ipsj.cls を作ってみました。
# upLaTeX なので pLaTeX では難しかった源ノ明朝・源ノ角ゴシックの利用が
# できるようになります。
#
# 無保証です。これを使った結果何が起きても責任は取りません。
